Methods of treating or preventing a disorder, or a complication of a disorder, of an eye of a subject, comprising contacting a vitreous and/or aqueous humor with a composition comprising a truncated form of plasmin comprising a catalytic domain of plasmin (TPCD) are disclosed. TPCDs include, but are not limited to, miniplasmin, microplasmin and derivatives and variants thereof. The methods of the invention can be used to reduce the viscosity of the vitreous, liquefy the vitreous, induce posterior vitreous detachment, reduce hemorrhagic blood from the eye, clear or reduce materials toxic to the eye, clear or reduce intraocular foreign substances from the eye, increase diffusion of a composition administered to an eye, reduce extraretinal neovascularization and any combinations thereof. The method can be used in the absence of, or as an adjunct to, vitrectomy.
A method of liquefying a vitreous and/or inducing posterior vitreous detachment of an eye of a subject having macular edema, comprising contacting the vitreous and/or an aqueous humor in the eye of the subject having macular edema with an effective amount of a composition comprising microplasmin, wherein the method results in liquefying a vitreous and/or inducing posterior vitreous detachment of the eye of a subject having macular edema.
A method of treating macular edema, or a complication of macular edema, of an eye of a subject, comprising contacting a vitreous and/or an aqueous humor in the eye of the subject with an effective amount of a composition comprising microplasmin, wherein the method results in vitreous liquefaction and/or posterior vitreous detachment in the eye of the subject, thereby treating the macular edema, or the complication of the macular edema, of the eye of the subject.
A method of performing a vitrectomy in a subject having macular edema, comprising contacting a vitreous and/or aqueous humor of an eye of the subject having macular edema with an effective amount of a composition comprising microplasmin, prior to or at the same time as the removal of the vitreous.
